Are these products safe?
Fat burners are not regulated by the FDA so companies can put whatever herb, vitamin, or mineral in them as long as the substance isn’t illegal. i don’t know of any long term studies on any one of the hundreds of fat burners on the market.
Do they work?
Many of these products have been shown to be effective for weight loss, though they may have negative side effects. Be aware these products can cause side effects such as rapid pulse, increased blood pressure, constipation, nervousness, sleeplessness, and lack of appetite.
Are they healthy to you and your weight loss goals?
The jury is still out on the health benefits of any fat burner. These products should be looked at as temporary fixes to weight loss. Most of them cause a decrease in appetite, which can lead you into a situation of not consuming enough calories on a daily basis.
If you aren’t eating enough daily calories, your body responds by slowing your metabolism, storing fat, and using muscle for metabolism. This can result in you losing weight, but muscle weight instead of fat. The goal in any weight loss program should be to keep the muscle, lose the fat.
Fat burners might help you lose some weight in the short term, but once you stop taking them you run a high probability of gaining the weight back, especially if you aren’t following a healthy eating plan and moderate exercise program.
